As our planet faces the realities of climate change, one of the most pressing challenges is the rising sea levels, posing a significant threat to coastal areas worldwide. A recent study led by Gonéri Le Cozannet and colleagues, including members of the CoCliCo team, highlights the urgent need for adaptation strategies to address this looming crisis.
The Inevitability of Sea-Level Rise
The research, published in IOP Science, underscores that a global sea-level rise of two meters is inevitable, the timing of which depends on our greenhouse gas emissions and polar ice-sheet melting. Even with stabilized global temperatures, sea levels will continue to rise for centuries. This scenario isn’t just a distant possibility but a near certainty, with significant implications for coastal communities, ecosystems, and infrastructure.
After Europe’s recent extreme weather events, including the warmest summer on record and severe floods, it’s crucial that we take action on climate resilience. Adaptation actions not only contribute to recovery and resilience but also help mitigate climate change, protect biodiversity, ensure citizen safety, and secure financial stability.

Why Immediate Action is Crucial
In response to the inevitable rise of sea levels, the study by Gonéri Le Cozannet et al. provides a comprehensive five-step approach to adapting our coastlines. Here’s how we can apply these strategies:
Adaptation Strategies for Coastal Areas
The study outlines several strategies:
- Prepare the Ground for Adaptation:
- Raise awareness and improve climate literacy among communities and stakeholders.
- Strengthen or create new governance institutions and mechanisms that prioritize coastal adaptation.
- Engage with local communities to involve them directly in the adaptation process
- Assess Risks and Vulnerabilities:
- Focus on long-lived assets and infrastructure that will be impacted by future sea-level rise.
- Pay attention to vulnerable coastal communities, ecosystems, and habitats, encouraging a two-way exchange of ideas to identify risks and vulnerabilities.
- Assess Adaptation Options:
- Identify all relevant adaptation options, including nature-based solutions and technological innovations.
- Evaluate the feasibility, cost-effectiveness, and potential co-benefits of each adaptation option, as well as their limits.
- Implement Adaptation:
- Prioritize options that offer high social, economic, and environmental co-benefits, and that align with sociocultural values and development priorities.
- Aim to implement adaptation measures neither too late nor too early, leaving options open for future generations.
- Monitor Adaptation Progress:
- Continuously monitor the implementation and effectiveness of adaptation strategies.
- Assess early signs of sea-level acceleration and map adaptation plans and actions to respond promptly.
- Progress an adaptive pathway to identify how current decisions contribute to long-term objectives, avoid future lock-ins, and maintain open options.
By following these strategic steps, we can establish climate services that support coastal adaptation to sea-level rise over decades to centuries. This iterative process requires us to think strategically about the different visions for coastal management areas and to act now for a resilient future.
The Role of Stakeholders
Coastal stakeholders, including governments, communities, and businesses, must acknowledge the reality of sea-level rise and act strategically. This includes planning for long-living infrastructure, adapting land-use decisions, and engaging in robust coastal zone management.
